Parts for your 2004 Daihatsu Yrv-Oil seals

2004 Daihatsu YRV oil-seals — what they do, where they are, and when to replace them

Oil-seals are absolutely fitted to the 2004 Daihatsu YRV. Technical references including the Daihatsu YRV M200 Series Workshop Manual (K3-VE/K3-VET engines), the Daihatsu M200 Parts Catalogue (Engine and Transaxle sections), and Aisin automatic transmission service literature list multiple oil-seals used throughout the engine and driveline. These include the crankshaft front seal and rear main seal, camshaft seals, and transmission/differential output shaft seals. So yes—oil-seals are relevant on this model.

On a 2004 Daihatsu YRV, oil-seals keep engine oil and transmission fluid where they belong while allowing rotating shafts to spin freely. They prevent leaks at high-wear interfaces like the crank pulley, cam sprockets, and gearbox output shafts. When they harden, wear, or groove the shaft, you’ll see weeping under the bonnet, oil at the bellhousing, or drips around the driveshafts—sometimes with a hot, oily smell after a drive.

There’s no set kilometre interval for oil-seal replacement
